Get the inside story on a first time gyno and uro check up


When I was asked to write a short article on Gynecology and Urology I was kind of surprised. What can you write about two of the most invasive but really embarrassing fields ever invented by any one? One is designed to look up female Yoo-Hoos and the other is designed to check male and female irrigation systems!

Potentially embarrassing? Why definitely, that’s a given!

But jokes aside, Gynecology is an extremely essential field which deals with doctors who charitably dedicated their lives to the repairs of female crotches. Sometimes they also deliver babies, and then they are generously called as obstetricians as well. But Urology is a medical specialty which deals with health problems related to the male reproductive as well as liquid waste plumbing system.

Many girls and women are worried about going to a gynecologist for their first time (every first time is kinda scary!) but it’s absolutely essential to get yourself checked at the first period and then every year to rule out any potential problems. Yes it does sound nasty but here’s a rundown of what is expected during a routine gynecology and urology check up.

· It’s best to get to know your gynecologist before your check up to know what you’ll be going through. Most first exams have a breast exam, urine test, pelvic exam and a detailed medical history.

· If your doctor is a male ask for a female nurse to stay in the room with you; its routine policy. Most doctors will not confide anything you ask for to your parents or any one else so it’s safe to clear all your doubts regarding contraception and sex with him. The doctor may also ask a whole lot of questions about your medical and sexual history; be as honest as possible as medical histories are confidential and this helps the doctor make an accurate assessment of your health.

· Next comes the pelvic exam. Relax! The doctor sees thousands of vulvas every day; day in and day out; its routine for him .You’ll be asked to change to a white examination gown and sit in an upside down saddle position. Kinda like sitting on a horse but this one is on your back with your legs raised.

· The breast exam is even simpler where the doctor gently palpates your breast to check for lumps .Breast cancer appears as a small painless lump and is the foremost killer of women world wide. So allow the doctor to do a good job. Do tell the doctor if you have a family history of breast cancer.

· Some doctors also insert a large spoon into your vagina to scrape your uterine neck. Relax! The process is entirely safe and is called as a PAP smear .Its designed to check for uterine neck abnormalities or cervical cancer. This is an entirely treat able cancer if detected early.

SO you’re done with your first gyno check up. Now’s the time for a urology check up.

Most urologists have a routine of first getting a detailed medical examination and history, and although they do deal with females they have a larger range of male patients who have to get their testicles checked for Testicular cancer, prostate checked for Benign prostatic hyperplasia as well as all other their male reproductive organs which include testes, epididymis, vas deferens, seminal vesicles, prostate and penis.

For a first time urology check up I would advise the following,

  • Most doctors prefer to start off with a detailed medical examination and history which is really useful to clear any doubts regarding health of the male reproductive system as well as to catch disease early on.
  • Just like a gynecology exam, urologists will also do a rectal examination to palpate the prostate gland, a general examination as well as an abdominal examination to rule out any abnormalities.
  • I would recommend a yearly examination for all males over the age of 20 irrespective of what the doctors say .Its better to be safe rather than sorry right! After all you don’t want to lose a testicle to testicular cancer, do you?

Ok I’ve really finished scaring you with the facts of a gynecology check up as well as a urology check up.

But seriously .Its better to get yourself checked as regularly as possible to avoid dangerous and untreatable conditions especially if you have an active sexual life.

Be aware and remain healthy!

Common features of the Lathe tool


There are many varieties of lathes used widely for industrial as well as indoor purposes. But every lathe has some common features. A stand for a lathe is not common for all lathe types. There are lathes without legs or stand, which can be fitted on the floor. The height of the lathe bed will be suitable for working. Some small lathes are suitable to place on a work bench or table. These types of lathes usually do not require any stand.

The ‘bed” is almost kept horizontal in all lathes except in some CNC lathes in which bed is kept as a vertical beam to make the chips or swarf to fall freely while working. “Head stock” is kept usually on the left end of the bed and it contains spinning bearings for high precision cuttings. This end is where the operator faces the lathe while working on it. Spindle is an axis parallel to the bed, which is usually hollow. This spindle is the one which rotates within the bearings. There is an interior Morse taper or exterior thread on the “inboard” of the spindle, which helps to hold the working material being placed on the spindle with the help of accessories. It is always facing towards the bed of lathe. Spindles may also contain exterior threads on the “outboard’ end, hand wheels or other accessories or mechanisms. Spindles are powered to the maximum, for the excellent movement of work piece.

Spindle is operated by power from flywheel and treadle by a foot. The other method of operation is by using a belt drive connected to a power source. The power source is an electric motor and it forms an integral part of modern lathes. It is usually fitted in the headstock or beside the headstock. There is a re-lockable loose head placed suitably on the bed, which contain a non rotating barrel. It can slide in a parallel fashion to the axis of the bed. It may contain some accessories for the firm gripping of various tools. It is usually hollow.

The “cross slide” is a flat piece of material sits on the bed in metal working lathes. It removes the material for cutting from the working piece by a cutting tool. Some lathes contains lead screw to move the cross side to the length of the bed. Metal spinning and woodturning lathes do not contain cross slides. They have “banjos” instead of cross slide. The position of banjos is changeable by hand. The tool post and tool rest are the two parts of banjos.

There are some accessories connected to lathes for better functioning. A face plate is a flat plate used to mount the work piece. Like wise faceplate dogs are used to protect the work on work plate. The work piece can directly mount on a mandrel using a three or four jaw chuck. Collect is used to hold the work piece in precision important works. It is used to hold cylindrical work pieces. There are other collects for holding work materials of different shapes. A spur drive is another accessory to hold soft work piece at the headstock.
